6801-2RS Deep Groove Ball Bearing For Compact Electric Motors & Precision Mechanisms | 12×21×5 mm

The 6801-2RS is a Compact and Sealed Deep Groove Ball Bearing designed for applications requiring reliable, maintenance-free operation in challenging environments. Featuring integrated double rubber seals (2RS) on both sides, this bearing provides excellent protection against dust, moisture, and fine contaminants. The effective sealing retains lubricant, minimizes friction, and ensures smooth, long-lasting performance. With its slender 12mm bore and narrow 5mm width, it is an ideal solution for space-constrained designs in small electric motors, gearboxes, and precision instruments.



6801 2RS Deep Groove Ball Bearing 12×21×5 mm | ISO 18 Series – Extra Light | Double Rubber Sealed

This precision bearing incorporates a reliable deep groove design and full-contact rubber seals, making it suitable for applications where environmental sealing is as critical as performance. The 6801-2RS supports moderate radial loads and can accommodate light axial loads in both directions. Its slim profile, combined with effective sealing, makes it a preferred choice for small drives, medical devices, office automation equipment, and other applications exposed to dust or occasional moisture.
